How to grab CAPTCHA off webpage? - SirBuck777 - Jul 10, 2013

http://api.solvemedia.com/papi/challenge.noscript?k=YofwLNxxBvEMSuDl.BVlHV-zV-MV8L61

I'm using DeathByCaptcha to solve CAPTCHA images. However, does anyone know how I can actually download the image in order to upload it to DeathByCaptcha?

I'm using PHP for this.

you grab the html with something like curl, then grab from the html the image link and download the image.

That is no problem. For example, on Linux you can do this:

Code
curl 'http://api.solvemedia.com/papi/challenge.noscript?k=YofwLNxxBvEMSuDl.BVlHV-zV-MV8L61' -s | grep -o -e "<img src=\"[^\"]*" | head -n1 | sed "s/<img src=\""/http\:\\/\\/api\.solvemedia\.com/g | xargs curl > captcha

It will save the captcha to the file "captcha".

No, but I told you how to do it. If you know VB then it should be easy to do it for you....

1. grab the webpage
2. grab the img src
3. grab the image
